Chapter 2. Knowledge Mapping: Foundation

Invisible college, which consists of a small group of highly productive and networked scientists and scholars, is believed to be responsible for growth of scientific knowledge. By analyzing scholarly publications of these researchers using select content analysis, citation network analysis, and information visualization techniques, “knowledge mapping” helps reveal this interconnected invisible college of scholars and their ideas. In this chapter, we discuss online resources that are often used for such analyses, including: abstracts and indexes, commercial full-text articles and digital libraries, free full-text articles and e-prints, citation indexing systems and services, electronic theses and dissertations, patents, and business and industry articles and reports. These resources can be used to identify important authors and inventors, publications and publication outlets, institutions, countries and regions, and subject and topic areas over time.
